There are known closed loop plpellne conveyors wlth wheeled containers. These are at least ten variants of them to date. Essentlally~ these systems have two tubes and loops at the ends. At the ends are performed the loadlng and unloadlng operatlons. Unloadlng speclally is performed ln a long space, at least 2 - 3 times the length of a contalner -elther by rotatlon around the axis or bottom dumplng.
Propulslon ls achieved by blowers and valves-gate~ or flap type. The maln dlsadvantages of these known system are:
a) the loops at the end~ are blg, taking too much space, fact that ls ob~ected by the end user;
b) the valve system sometlmes is prone to accldents, the contalners are smashing the valves, belng they gate ~a1ves or flap valves.

profile or a combination of these; also, rigidly connected to the said rod, there is a fixed arm/dog; also, on the gondola there is a retainer dog articulated to gondola, also there is on the gondola a spring pressing the said retainer dog against the said fixed arm/dog, keeping/retaining it in a closed position, implicitly keeping the sliding piston with rod like object in cruise pressed down position; also on the front solid circular disk there is an articulated lever, which is pressed in or against a rigid circular sector object, which is rigidly connected with the said vertical tube; also on this rigid circular sector there is a slot, where the said articulated lever is entering and by this is able to lock together the gondola and the assembly made of wheels, sleeve bearing; vertical tube and other associated objects; also, in another variant it is possible that the said fixed arm/dog is entering into a slot, cut in the said front solid circular disk, so that the gondola not to be able to rotate left or right in cruise position; also, a similar arrangement to be placed at the other and of gondola; also, opposite to the said fixed arm/dog - also rigidized to the said rod of the piston with rod like object, there is another fixed rigid indexing object entering in the guides placed on the said superior flange, so that in cruise position, the fixed rigid indexing object to be able to preclude the rotation of the piston with rod like object; also being possible that the said fixed rigid indexing object to be able to enter not only in said guides on the superior flange, but also being enough long to enter in a slot in the one of the front or back solid disks of containers/gondolas, by this helping to preclude the rotation of the gondola in relation with the vertical tube and the wheel assembly; also the containers could have circular gaskets/disks in front and back, these gaskets/disks being kept into position of work by rigid arms fixed to the said vertical tubes; also the containers have articulated to the front or back solid disks rigid followers or arms, their rotation being possible only in a plane parallel with the said solid disks and this rotation being limited by a rigid prominent object, fixed to the said disk where the follower is articulated; also, the said wheeled containers could have two or more rolling wheels in front or in the back and also they can have lateral roller balancing wheels fixed to the body of gondola; also, the containers could have in front and back only one steel double flanged wheel attached by a frame to the said sleeve bearing, this double flanged wheel being able to roll on a steel rail placed at the bottom of the tube; also, the said containers could have attached to the said frame two smaller lateral balancing wheels, which are rolling on the interior surface of the tubular guideway, these smaller lateral balancing wheels could be pressed by springs against the surface of the tubular guideway.
c) transfer loops to transfer the containers from one tube to another, in this case the containers simply being forced to roll suspended on the rolling means inside of the curved monorail structure of the transfer loop;
d) an empty containers extractor mechanical conveyor placed outside of the tubular guideways to extract the containers from the tubular guideways, this extractor mechanical conveyor having dogs to entrain the containers and having control means to correlate with the rest of the process, so that to be able to keep a container unmovable or movable at low speed just in the exit of the tubular guideway by simply slow movement or by simple stopping if necessary, so that all the time the end of the tubular guideway to be closed by a container/containers - that is to have there a dead end so that if other containers are coming from upstream to stop/brake in the said dead end by the counter pressure generated there;
e) propulsion means, in this case a main propulsion blower, which is sucking air from the coming tubular guideway or directly from the atmosphere and reinjecting the said air into the return tubular guideway; also the propulsion means include a main injector loading mechanical conveyor with dogs outside the return tubular guideway, which is pressing the containers one by one with the dogs inside the tube.
f) a loading unit, essentially made of a feeder and surge hopper placed close to the said main mechanical conveyor which is loading the bumper to bumper slow moving containers in a similar way with an unit train.
g) an unloading unit, made of an incoming accumulator tube, essentially made of a tube with an input end and output end connected to be the main incoming tube at the input end by a flange or simply welded to it, the main incoming tube having or not a vent close to the said flange,also the said incoming accumulator tube having a control valve to check the pressure inside of it; also at the output end of the incoming accumulator tube and outside of it being an extracting conveyor with means to catch, entrain emerging containers and means to correlate with the rest of the process in the overland pipeline conveyor, so that to keep all the time the output end of the said incoming accumulator tube closed all the time with slow moving containers or with stationary containers, the said incoming accumulator tube being inclined with an angle in the direction of movement of containers that is in the direction of output end of the said incoming accumulator tube, so that the containers are continuing to roll even without pneumatic propulsion, immediately they are entering inside the said incoming accumulator tube; also, after the said mechanical conveyor there is a monorail loop where the containers are entering with their upper rolling means and perform unloading and transfer to the second, return tube, at the entrance of the tube being another mechanical conveyor called the unloading injector mechanical conveyor with means to entrain, drive the containers which pushes the container inside of the return tube where they are taken by a main propulsion unit and pushed away along the return tube.
